A highly bent triarylborane, 9-boratriptycene, was generated in solution by selective protodeboronation of the corresponding tetra-aryl boron ate complex with strong Brønsted acid HNTf2 . The iptycene core confers enhanced Lewis acidity to making it unique terms structure and reactivity. We studied stereoelectronic properties 9-boratriptycene quantifying its association small N- O-centered bases, as well sterically hindered phosphines. resultant adducts exhibited structural, spectroscopic,...
The rational design of a geometrically constrained boron Lewis superacid featuring exceptional structure and reactivity is disclosed. It enabled the formation non-classical electron deficient B-H-B type bonding, which was supported by spectroscopic structural parameters as well computational studies. Taming pyramidal acid electrophilicity through weak coordinating anion dissociation series highly challenging chemical transformations, such Csp2 -H Csp3 activation under frustrated pair regime...
Quasi-spherical undoped ZnO and Al-doped nanoparticles with different aluminum content, ranging from 0.5 to 5 at% of Al respect Zn, were synthesized. These evaluated as photocatalysts in the photodegradation Rhodamine B (RhB) dye aqueous solution under UV-visible light irradiation. The nanopowder annealed at 400 °C resulted highest degradation efficiency ca. 81% after 4 h green irradiation (525 nm), presence mg catalyst. samples characterized using ICP-OES, PXRD, TEM, FT-IR, 27Al-MAS NMR,...
A new polystyrene-type resin loaded with pincer-type imidazolium ionic tag has been very effective in the immobilization of [PdCl<sub>4</sub>]<sup>2−</sup> palladium complex leading to a low leaching metal during its use flow.
Polyhedral oligomeric silsesquioxane functionalized with imidazolium chloride peripheries was synthesized and successfully used as a catalyst for CO<sub>2</sub> conversion.
Proline has been widely used for various cocrystallization applications, including pharmaceutical cocrystals. Combining enantiopure and racemic flurbiprofen proline, we discovered 18 new crystal structures. Liquid-assisted grinding proved highly efficient to explore all the variety of forms. A unique combination state-of-the-art characterization techniques, comprising variable temperature in situ X-ray diffraction ball-milling, along with other physicochemical methods density functional...
A resin-bound 1,2,4-triazolium ionic tag has been used as support for the preparation of solid palladium nanoparticles (Pd(0)-POLI-TAG-Pd). Owing to pincer-type architecture triazolium ligand, stabilization a high amount (16 wt %) possible. The catalytic system fully characterized and in low amounts (i.e., 0.1 mol % loading) representative Heck–Mizoroki cross-coupling processes. negligible release metal was demonstrated, activity obtained over more runs. Besides, protocol optimized use safe...
The synthesis, properties and structural requirements for atropisomerism at the C−B bond in boron Lewis acids such as triarylboranes have been understudied so far. We report first series of atropisomeric constituted a naphthyl rotor dihydro‐9‐bora‐anthracenyl stator subunits, connected by stereogenic axis. Through systematic crystallographic, kinetic, photophysical quantum chemical studies, mechanisms, rates barriers diastereomerization enantiomerization were determined. orthogonal...

Bifunctional carbon‐based acid catalysts presenting Brønsted and Lewis sites in different proportions were synthesized by grafting mesoporous aluminosilicate patches coexistence with benzyl sulfonic moieties on the solid’s surface. The final bifunctional systems obtained development of a methodology allowing production discontinuous metal‐oxide layer carbon substrate using silica as model oxide before applying optimized procedure for desired alumino‐silica patches. Patches necessary to...
